Together with certain game configurations, the Quest Pack salamander auras can cause the game to crash. Notably, this includes the GOG version in its default configuration. Vanilla BG2 and BG2: EE do not appear to be affected. The salamander auras are installed with the Creature Improvements components.
This hotfix will change the salamander auras to work (without known issues) on all game configurations. There is no need to start a new game after installing it, and it will fix crashing instances you've already encountered.Download link
